ATT'o KNE) Patented Dec. 20, 1949 UNITED STATES FATENT OFFICE DISHLIKECONTAINER FOR DENTAL DRILLS AND THE LIKE Walther Roos, Basel,Switzerland Section 1, Public Law 690, August 8, 1946 Patent expiresOctober 24, 1966 2 Claims.

Dish-like containers in use up to the present, in which dentists placetheir drills or other rod shaped implements, ready for use, comprise afiat shaped container body, in which are provided one or morecompartments formed by recesses having a rectangular horizontal sectionand containing the different drills or the like. These compartments areprovided with vertical side walls and a flat bottom, on which aresuperposed the drills, so that the upper drills cover the lower ones. Ifthe dentist wishes to withdraw a special headed drill from the saidcompartment, he must search for the same with pincers among the pile ofdrills in this compartment, since the heads of the lower drills are notvisible.

According to the present invention, this drawback is eliminated by thefact that at the frontal side of the compartment or compartments of thecontainer, against which are directed the rear ends of the drills, thereis provided an inclined abutment surface, against which may bear thedrills with their rear rod ends, so that the head ends of all the drillsare in staggered formation and are clearly visible.

The accompanying drawings show by way of examples different forms ofembodiments of the object of the invention.

Fig. 1 is a plan view of a dish-like container according to a firstembodiment;

Figs. 2 and 3 show, in a larger scale, a longitudinal section and across section along the lines 11-11 and III-III of Fig. 1;

Figs. 4, 5 and 6 show further cross sections, and

Fig. 7 shows another longitudinal section of a further form ofembodiment of the container according to the invention.

The dish-like container according to Figs. 1, 2 and 3 includes a fiatshaped container body a comprising four compartments b for longer dentaldrills and three compartments 0 for shorter dental drills. Thesecontainer compartments are formed by recesses or depressions ofrectangular plan view. Each of these container compartments is providedwith an inclined abutment surface b respectively b at its right frontalside as seen in Fig. 1. Inclined surfaces 1: and c are also provided atthe two longitudinal sides of the container compartments, whose sectionline, lying in the central longitudinal plane of the containercompartments, slants downwardly from the left hand frontal side. Thesection lines of the three inclined surfaces b b, b intersect, as shownin Figs. 1 and 2, at a point of intersection 0 which coincides with thedeepest point of the corresponding container compartment. The drills ofthe same length are placed in the container compartments. As a result ofa'slight shaking of the container, the drills settle as shown in Fig. 2with their rear rod ends bearing against the inclined abutment surfacesb, so that the head ends of all the drills are visible, as seen fromabove, in a staggered formation. The container compartments may haveother longitudinal and cross sections than those shown in Figs. 2 and 3.For instance, Figs. 4, 5 and 6 show other sections which may also betaken into consideration and which may be rectangular, semi-circular orpolygonal. Fig. 7 further shows that the bottom surfaces of thecontainer compartments, on which the drills rest longitudinally, neednot necessarily be inclined, as is the case in Fig. 2, but may also befiat or horizontal. In any case, however, an inclined abutment surfaceis provided, for the above stated purpose, at the frontal side of thecontainer compartments, against which are directed the rear rod ends ofthe drills.

What I claim is:

1. A receptacle for dental drills and the like comprising asubstantially fiat shaped body, a recessed compartment of substantiallyrectangular shape in said body, said compartment having an inclined endportion sloping downwardly toward the center thereof providing anabutment surface for the rear ends of the drills, said compartmenthaving inclined longitudinal sides: sloping downwardly toward the centerthereof and intersecting along the central longitudinal axis of saidcompartment, whereby drills placed in said compartment are held instaggered relationship having the head ends thereof individuallyvisible.

2. A receptacle for dental drills and the like as claimed in claim 1,wherein the line of intersection of the said inclined longitudinal sidesslopes downwardly from the end of said compartment remote from saidinclined end portion toward said inclined end portion, the deepest pointin said compartment being at the point of intersection of said inclinedend and the line of intersection of said inclined longitudinal sides.
